mnovnmm' m WATER-COOKS.

I t I I I I The Schedule referred to in these Letters Patent and rnaking part of theaazne.

To all 'whom it may concern V Be itknown that-we, llEsnY S, Non'rn nod 'lnoruns THOMPSON, ofMiddlclown, in the county ofMiddlL-scx, and in the State of Connecticut,have invented certain new and useful Improvements in Filters and Attachment for'Water-Cocks'; and do hereby declare that the following is a full, clear, and exact description thcreof, reference being had to the acwmpa-nying drawings, and to the letters of reference marked thercmn The nature of our invention consists-in the mode of attaching a lilh-r or hose ton sni0otli-hib cock, by means of an India-robber sleeve, which, at the same time, serves as a scli packing; also, in the construction and general nrmngelnent. of a filter, all of which will be hereinafter more fully set forth.

In order to enable othcisskilled in the art to which our invention.appertnins, to make and use the same, we

will now proceed to'descn'bc its construction and operation, referring to the annexed dnuvings, which form a part of this specification, and which represent a side view, part in section, of our invention;

A represents a. water-exalt, made in any of the known and usual wuys,'\vith a smooth bih, that is, one on which-there are no screw-t-lueads made to fasten a hose orfiltcr.

' It is well known finite-large majority of-the waterco'cks mnde :mdjn use have no sclmv-tln'eads upon the bib for a hose-or liltemittachment, and our invention is expressly designed for these kinds oflwatcr An India-rubber sleeve or nut, B, is placed on or I around the bib of the water-cock, said sleeve being provided with serew-threznls on the outside.-

The chamber a of the filter G, where it is attached to the cock, is made tapering, and provided, on its inside, with screw-threads, of size corresponding with the threads on the rubber sleeve.

The sleeve- B, being made of rubber, is, consequently,

tiexible, and can be attached to cocks of various sizes, a'nd,as we make them tapering, it will admit of a filter being attached when the bibs of the cooks vary considerablyin size.

-The chamber of the filter also being tapering, the

further it is screwed up, the more firmly in will bind the'mhbcrslecve to the bill of the cock.

This mode of coupling is valso srli packing. As the sleeve .is made ofirubbcr, it packs itself around the smooth bib of the cock and the screw of the filter, so

that not a dropof water can look around cit-her. -Ine manner, a hose can be attached to the smooth bib of awater-cock. v 'The filter 0 consists of two strainers, as follows:

The lower strainer, b, is made in the shape of a dome, and placed over the lower opening in the filter. By makingthe lower strainer of this shape, we obtain. a greater number of meshes for the. water to pass I through than by the common flat strainers.

Over the lowerstruinegh, weplaoc a cap, 0,.mzwof sheet-bhiss, tin-plate, or other suitable material,

pefl'omtcd on the sides with a number of holes, and covered with cloth or its equivalent. This keepsthe;

sand from washing into the meshes, and clogging the lower strainer, and also serves to protect and keep it discharge-hole, at the lower partof the filter O, in.

which the strainer -is.plaeed, and firmly secured by filling it with water proof cement, or other suitable means. v

In the upper part of the filter, below the chamber a,- is a shoulder or circular flange, c, on which the upper strainer rests. v

This stminer consists of a circular peribmted plate,

f, and a circular piece of wirej'cloth, g,which'cnn be easily removed. '7 v "lo charge the filter with sand or other filtering-muterial, remove the rubber sleeve B, which we make a part of the filtef, by unscrewing and hiking it onto! the chamber a. Then, with thepointv of n knife or other suitable instrument, the upper strainer can be taken out,'and thefiltering material poured in, after which the upper strainer must be put backto its place. To clean the filter out, remove, in the same way,

the upper stiainen'and loosen the-sand, 8w. Thenreverse the filter, and hold the discharge-hole to the water-cock; nnd, by letting the water" run in that way, 7 w it will loosen the sand from the cap or shield c,- and,

by blowing through the discharge-hole, and thoroughly washing and rinsing t, all the old filtering-material may be entirely cleaned out of it.

Having thus fully described our invention,

.What we claim as new, and desire to secure by Let-- ters Patent, isit I 1. An India-rubber slecveornug'with a. hole through its ccnt1e,-and screw-threads on the outside, for the purpose of attaching a water-cook filter, or coupling a as herein set forth.

2. The filter-O,-constructed, as described, with the tapering chamber fat the npper'end, and an annular hose to a water-cock with a smooth bib, substantially groove, :1, around the .dischaige-hole at the lower end,

in combinationwith the rubbersleeve or nut B, for the purpose of attaching the filter toa water-cock with smooth. bib, substantially as heinin'setforth,

In testimony that .we elaim'the foregoing, we have hereunto set our hands-this flothday of August, 1868;

HENRY S. NORTH.
